Laravel显示所有用户并检查是否属于Bans表

嗨，我在管理仪表板上工作 我想显示所有用户，并检查用户是否阻止从bans表获取有关ban的信息 im使用cybercog/laravel ban禁止用户 拉威尔5.8

所以我有两张桌子 用户表和禁止表

Bans表在名为：BANABLE_id的列中具有绑定用户的用户id

如果使用了错误的关系，则应使用多态性。看看下面的链接。

大概是

用户模型

public function ban()
{
   return $this->morphOne('App\Ban', 'bannable');
}

Ban模型

public function bannable()
{
   return $this->morphTo();
}

获取控制器中的所有用户

定义

use App\User;

然后

然后，您可以foreach它并对每个对象调用ban（）方法

foreach($users as $user)
{
//return associated ban model
$user->ban;
}

或者，为了获得更好的性能，请使用

User::with(ban)->get(); 

这大大减少了SQL调用的数量。它检索具有ban模型的所有用户。请看下面链接中的急切加载


希望有帮助。：）
 很抱歉，我是laravel的新手，非常感谢，如何在控制器中获取并显示它？THX ban（）方法不兼容，但它可以（应该）已经在Bannable trait中实现，请尝试在User:：classlook中注释“ban”方法如果有ban（）的话在trait中查看methodi注释了ban方法并运行它获取错误：使用未定义的常量ban-假定为“ban”（这将在PHP的未来版本中引发错误）
